Q 16Q 16
Explain the major differences between bitmap and vector images.
Bitmap images are created from a matrix of pixels, dots containing color information, while vector images are created from mathematical representations of Bézier curves. Bitmaps are well suited for photographic or continuous tone images, while vector images are more appropriate for illustrations or graphics such as logos. Scaling bitmaps larger results in lower resolution, while vector images may be scaled without loss to resolution.
